Supreme Villain Rafaam

Supreme Villain Rafaam and scheme permanents
you control are indestructible.
At the beginning of each end step, you may search
your library for a scheme card and put it into the battlefield under your control, then if you
control 5 or more schemes you win the game.
Whenever Supreme Villain Rafaam leaves the battlefied, return it to the battlefield tapped at the beginning of your next end step.
